We report a rare case of bile duct carcinoma associated with pancreaticobiliary maljunction (PBM) without choledocal cyst. A 52-year-old woman was admitted to our hospital with abdominal pain and jaundice. CT and MRI showed an enhancing mass in the middle portion of the common bile duct. ERCP and MRCP showed PBM without choledocal cyst and stenosis in the middle portion of the common bile duct. As pathological findings, tubular carcinoma was seen at the distal bile duct but no cancerous lesion was found in the gallbladder.
